A wonderfully playful work with a killer song and a great square sense of humor, the film is, as Ben notes, an "early precursor to quite a common music video style" of showing the different instruments and players (in this case, just Mr. Lavarents in several guises) within their own subframes. It must have been quite difficult to make in pre-digital 1970, especially for an amateur filmmaker. But like all good works, you don't sense the effort; it just feels breezy and jolly and amusing all around.
